Usage profiles and component reliability are two important factors in software system reliability estimation. To assess the sensitivity of a system’s reliability to the usage profile and to the reliability of its components, a Markov based system model is used. With the help of this model, the maximum sensitivity to one change or the statistical sensitivity to many independent changes can be estim

The study of posture dynamics is important not only to understand disorders of impaired equilibrium and protective reactions to unexpected displacements of the human body, but also to the design of prosthesis and functional neuromuscular stimulation as aids to patients with impaired postural stability and locomotion. Coordinated control of the body segments is a complex aspect of motor behavior, o

I am so old that Post-Mortem is a well-known technique for debugging programs. And so old that when I started teaching as an assistant, pedagogy did not exist - we were just "thrown into the deep end of the pool and told to swim". So it seemed obvious to me to turn Post-Mortem into a pedagogical technique for debugging and improving my teaching. To first dump data about what happened and then anal

Video data and the tools for automated analysis have a great potential to be used in road traffic research, particularly road safety. In this project a video dataset is built and made public so that researchers can evaluate their algorithms on it. The dataset focuses on the traffic research applications (data from real research projects) and provides recordings of the traffic scenes, meta-data, ca

Based on a case study of a telecom company’s transition towards more software value in their products, we describe and discuss SCM issues related to when traditional manufacturers go from a “hardware focus” to a mixed product configuration. Although software supply chain is not much discussed in logistics, it seems that logistics/SCM frameworks also fit many software supply issues. A specific soft

In this paper, we investigate the design of pulse shaping UK filters for impulse radio ultrawideband (UWB) communications systems. The goal of the shaping is to meet an arbitrary spectrum mask, e.g., the mask mandated by the FCC for UWB emissions. Compared with classical FIR filter designs, the current problem introduces three new challenges: (1) it is minimax with quadratic constraints, (2) a sin

Based on a survey of waste sorting behaviours and perceptions of residents in southern Sweden, we discuss how physical environment, gender and knowledge affect the actual sorting activities.
